Fluid Power

Double Acting Cylinder

The fluid from one side fills more on one side to extend it or retract it.

Fluid Power Compare and Contrast

Positive Benefits

  • They can push/lift heavy things that a regular system might not able to.
  • Both are low power
  • Pneumatic systems have a light to moderate load capacity, useful for those loads.
  • Hydraulic systems can can lift heavy loads.
  • Pneumatic are smooth

Similar Components

  • Tank for storing air or fluid.
  • Power (Battery or power supply)

Negative Drawbacks

  • Pneumatic can’t push with as much force since air compresses more.
  • Hydraulic systems can leak and make messes.
  • Hydraulic systems don’t work well in clean rooms.

Fluid/Air Distributed

  • Fluid in a hydraulic system goes from the reservoir to the pump and them to the hydraulic motor.
  • Air in a pneumatic system goes from the main tank to the buffer tank, then to the sport value, it then goes to a piston.

Unique Components

  • Air compressors, 5-port valves, double-acting cylinders, and pistons are unique to pneumatic systems.
  • A pump and hydraulic motor is unique to hydraulic systems.
